Specification of Letters Patent.

Patentedjune 2,1908.

application filed March a, 1906. Serial No. 304,994.

Washington, in the District of Columbia,

' view of the piano have invented certain new and useful Improvements in Note-Sheets forAutopneumatic Piano-Players; clare the following to be afulhclear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention has reference to;

piano ayers and it aims to provide an imrover note sheet adapted especially for use 1n connection with the particular form of tracker disclosed in my co-pending a )plication for patent on piano players, filed on or about March 7, 1906, Serial No. 304,739.

The tracker, which is likewise shown and described in this application, is provided with a double series of orifices,one for the melody andthe other lorthe accompaniment notes of a selection, there being a separate vacuum chest for each series and a communication between each oriiice and the corresponding vacuum chest.

.It is the object of this invention, therefore, as above stated, to provide a note sheet designed for use in connection with a tracker of such construction, the predominant characteristic of the sheet residing in the provision in each section of the sheet, of a perforation corresponding to each note of the corresponding part of the selection to be played.

The invention will be readily understood from a consideration of the following-detailed description and from an inspection of the, accompanying drawings in which like parts are designated by corresponding reference numerals, throughout the several'views.

' Of the said drawings, Figure 1 is a plan view of a portion of a note sheet constructed in accordance'with thepresent invention; Fig. 2 isa similar view of slightly modified form thereof, Fig. 3 is a vertical sectional which forms the subject of the above mentioned application, Fig. 4 is an enlarged detail view of the tracker with which the preferred form of note sheet is used, the latter is a similar view of a modified form of tracker and the note sheet used therewith.

As regards the piano player itself, which is shown in Fig.3, a detailed description of the elements thereof will be found in the applicaand I.do hereby do being .likewise shown, Fig. 5v

tion above identified, and as the instrument as a whole forms no part of the present 1nvention, a full description thereof has not been included in this application.

In the drawings therefore D indicates generally the keyboard, E the tracker, and A the note sheet which travels across the perforated front face thereof in the usual manner, each perforationororiiice of the tracker having a separate duct connection dwith the proper vacuum chest G or H, from which the air is exhausted by the pedal-operated 'bellows mechanism, not shown.

The improved tracker is somewhat longer than the tracker now in use, and is provided with a single line of orifices divided into two entirely separate series B and C, one following directly after the other, .there being an orifice in each series corresponding to ap-' every key of the key-board, or

proximately to be exact, each-series contains 65 orifices, each of which is connected by its duct (1 with the corresponding primary pneumatic, disposed within the corresponding vacuum chest. As above stated, two separate vacuum chests are made use of in the present invention, one of which is used for the melody of a composition, and the other for the a'ccompaniment, each chest-having means of communication with the bellows.

The note sheet used in connection with the tracker above described, in its preferred form, is provided upon one side of its middle, considered longitudinally, with perforations B and at the opposite side with )erforations C, the dotted line appearing in ig. 1 being for the purpose of illustrating the line of de marcation between the series of perforations. In the modified form of sheet shown in Fig. 2, the series of perforations B is subdivided and one of thesubdivisions is located upon each side of the series of which series, in this instance, is located within the boundary of the dotted lines shown in the figure, the boundary lines of the series being located at equidistant points from the side edges of the sheet. In practice the perforations B and C constitute respectively,

the melody and accompaniment notes of a composition. Therefore, owing to the fact that the tracker includes two separate series of perforations, controls the entire number of keys of theinstrument, and that one sectionof the note perforations C,

each of which independently sheet contains a separate perforation for each and every note of the melody whilethe other section is similarlypro videdwith a perfora tion corresponding to each and every note of the accompaniment of the selection to be -played,'it will be apparent that either part of the selection can be played and accentuated absolutelyinde endently of the other.

' In-the modi. ed form of sheet, the broad central section contains all the accompani merit-perforations, while the-two side sections jointly contain all'the melody perforations, the modified form of sheet being used only in connection with the modified form of tracker, as .will be understood.

Whatis claimed, is,

1. The combination, in apneumatic pianoplayer, ofa perforated note sheet, a tracker and sound producing means, the note sheet and tracker being each provided with a plurality of separate divisions, the divisions of thenote sheet corresponding to the melody and accompaniment parts of the selection to.

.be oft pletely cover the correspondingdivision of the tracker.

2. The combination, with a trac,ker,"and

- sound producing means, as herein described,

of a perforated note sheet having a pluralityof divisions, one of which divisions contains allof the melody perforations and the other of which divisions contains all of the accom-- paniment perforations, the melody division of the sheet containingperforations corresponding to tones Within thecompass of the accompaniment.

3. The combination, with a tracker, and

sound producing means, as herein described,

of a perforated notes'heet having a plurality of divisions corresponding respectively to the melody and 1 accompaniment arts of the selection tobe played, the me ody and accomp niment divisions containing all of the melody and accom animent perforations re- (spectively, the meibdy and accompaniment ivisions of the sheet containing erforations corresponding respectively, eac to tones within the compass of the other.-

4. The combination, in a pneumatic pianoplayer, of a perforated note sheet, a tracker, and sound producing means, the note sheet having a plurality of divisions each of which contains a perforation corres on'ding to each note of, the selection to be p ayed.

5. The combination, in'a pneumatic pianoplayer of a perforated note sheet, a tracker, and sound producing means, the note sheet and the tracker each having a plurality of corresponding divisions, each division of the tracker having a duct corres onding to each note of the selection to be p ayed.

6. The combination, in a pneumatic pianoplayer, of a perforated note sheet, a tracker, and sound producing means, the note sheet having a plurality of divisions one of which divisions contains all the melody perforationsfand the other of which divisions contains all of the perforations of the selection to .be played, the tracker being provided with a series of ducts having a plurality of independent divisions, each of which contains .a,"duct corresponding to each note of the selection.

In testimony whereof, I affix my signature, in presence of two'witnesses'.
